Vicarious liability refers to a situation where someone is held responsible for the actions or omissions of another person. In a workplace context, an employer can be liable for the acts or omissions of its employees, provided it can be shown that they took place in the course of their employment.
However, this ruling makes it easier for customers of a business who are assaulted by staff - or affected by staff who commit any unlawful act whilst on duty - to hold the employer business liable.
The Supreme Court has sent employers a wake-up call. It has broadened the law which holds employers vicariously liable for the acts of their employees who commit a crime whilst at work.
